David M
Not a direct fit for aftermarket fabricated intake manifold.

I specifically bought this unit to use with a Summit fabricated intake for a 5.3 (truck) LS1 and immediately ran into 2 problems; the mounting brackets are too long for the associated holes in the manifold and need to be cut down, and the crossover tube hits the back of the alternator and cannot be run in the front as usual. The way I am having to get around these issues is to cut down and refab the mounts, then run the crossover at the rear and feed my fuel line to the front right and put the block-off behind the alternator. I can do this because it's a new build but on a retrofit this will not work.
